While walking in the winter, I used to stick my V3 and V4 in my gloves so that they were resting in my palms. I did this because they were getting rather cold just in my jacket pocket. I used to alternate who went in my glove and who went in my pocket, but then I just put them both in since I had two hands. Well my hand would sweat and the screen would fog up, which worried me. Also, since this was winter and somewhat icy, I was further worried by the possibility of falling, putting my hand out to steady myself, and busting my tamagotchis because they were in my gloves. Now I just leave them on pause when I go walking, much safe either way.
